This invention relates to coating apparatus and is especiallyuseful in applying an adhesive to strips ofmaterial.

In the manufacture of rubber footwear many strips or pieces of rubberized fabric or rubber composition must be assembled and the operations of assembling have been conveniently accomplished'by passing the work along a line of operators who adhere the pieces successively and .roll or press them into place.

The present invention provides means enabling the operator to apply adhesive to such parts uni- "iormly and without employment of both hands.

suspended as at 25 fromthe table l3 in a position to be engaged by the knee of an operator,

and connected to lever 23 by a link 26.

For removing excess adhesive from the work and for returning it to the container, a bar 30 is supported horizontally from and above the plate l5 over an opening 3! formed in the plate. As

v the article22 is dragged across the surface of surface by the bar andreturns to the container.

cessevaporation of the solvent, to provide uni- .form application of adhesive, to provide for removal of excess adhesive, and to provide efficiency of operation and facility of manipulation.

These and other objects will appear from the following description and the accompanying drawing.

In the drawing:

Fig. 2 is a plan view of the device.

Fig. 3 is a fragmentary sectional view of the cement applicator, cement scraper, and upper rear edge of the container. i

0f the drawing, the numeral I0 designates a container for a supply of liquid adhesive H such as rubber cement. The container is preferably provided with a flange i2 upon which the container may be supported from the margins of a work table l3 surrounding an opening it in the top of the table. A plate I5 having perforations it therethrough is secured at one end to ashaft i1 journaled for rotation about a horizontal axis in bearings i8, 89 formed on the container above the adhesive. The plate normally rests in the container within the adhesive so as to prevent drying of the adhesive thereon but may be raised to a position parallel to the surface of the adhesive and above its surface, as shown in Fig. 1. In this position, a foot formed on'the free end of the plate engages an inwardly directed flange 2| of the container preventing further movement in a clockwise direction as viewed in Fig. 1. When so lifted from the adhesive, excess adhesive will drain oil the plate through the perforations and over the edges leaving a amiform coating of adhesive which may be removed therefrom by contact with an article 22 applied thereto.

For lifting the plate l5, one end of shaft I1 is formed with a lever arm 23. Additional lifting The inwardly directed flange 2l' at the top of the container extends thereabout and in its innermost edge is downwardly directed, as at 3| so as to return any adhesive dropped thereon directly to the body H. of adhesive thereby preventing running of adhesive down the sidesof the container whereit might dry from evaporation.

from the scope of the invention as it not be upset.

In the operation of the apparatus, the plate 55 normally remains below the surface of the. adhesive'in the container where it is free from dust or dried deposits'of cement. When a part is to be cemented, the operator shifts a knee laterally against arm 24 thereby raising plate l5 above the container with adhesive thereon. Excess adhesive drains oil. The article is then dragged across the plate and over the scraper bar 30 to provide an even coating of adhesive on the article. v 7

Variations may be made without departing is defined by the following claims.

I claim: I

1. Coating apparatus comprising a container foradhesive, a plate normally submerged in adhesive within said container, means for raising said plate at will to a position above said container, and scraper means mounted on said plate to remove excess adhesive from an article.

2. Coating apparatus comprising a table having a recess therein, a container for adhesive STEPHEN D. KLYCE.
